not rotated binlog since restart
The binlog contains specially marked format description events to mark
when a master restart happened (which could have caused temporary
tables to be silently dropped). Such events also cause slave to close
temporary tables.
However, there was a bug that if after this, slave re-connects to the
master in GTID mode, the master can send an old format description
event again. If temporary tables are closed when such event is seen
for the second time, it might drop temporary tables created after that
event, and cause replication failure.
With this patch, the restart flag of the format description event is
cleared by the master when it is sent to the slave in a subsequent
connection, to avoid the errorneous temp table close.

after error in parallel replication
The problem occurs in parallel replication in GTID mode, when we are using
multiple replication domains. In this case, if the SQL thread stops, the
slave GTID position may refer to a different point in the relay log for each
domain.
The bug was that when the SQL thread was stopped and restarted (but the IO
thread was kept running), the SQL thread would resume applying the relay log
from the point of the most advanced replication domain, silently skipping all
earlier events within other domains. This caused replication corruption.
This patch solves the problem by storing, when the SQL thread stops with
multiple parallel replication domains active, the current GTID
position. Additionally, the current position in the relay logs is moved back
to a point known to be earlier than the current position of any replication
domain. Then when the SQL thread restarts from the earlier position, GTIDs
encountered are compared against the stored GTID position. Any GTID that was
already applied before the stop is skipped to avoid duplicate apply.
This patch should have no effect if multi-domain GTID parallel replication is
not used. Similarly, if both SQL and IO thread are stopped and restarted, the
patch has no effect, as in this case the existing relay logs are removed and
re-fetched from the master at the current global @@gtid_slave_pos.

Merged revision 5224 from mysql-5.6 and added a test case.

Bug#16620047 INCORRECT QUERY RESULT (AFTER SERVER UPGRADE)
|
| | |
|
| |
|
|
|
|
|
|
| |
After fix of MDEV-6728, the KILL signal is reset at the start of query
execution. This means that in this test case, we need to wait for the
to-be-killed query to have started; otherwise the kill signal can be lost,
causing the test case to fail.

innodb.group_commit_crash_no_optimize_thread
The test case deliberately crashes the server. If this crash happens in the
middle of a page write, InnoDB crash recovery recovers the page from the
doublewrite buffer, writing a message to the error log that is flagged as a
test failure by mysql-test-run. So add a suppression for this.

log_error my.cnf parameter defined
some checks were "if [ -n "$err_log" ]", others were "if [ $want_syslog -eq 0 ]",
so when both are set, error log file was only partially initialized.
To avoid this ambiguity we reset want_syslog when error log file is used.

mtr internally does the following:
1. $default_vardir=....
2. $opt_vardir=$default_vardir unless $opt_vardir;
3. $opt_vardir=realpath $opt_vardir unless IS_WINDOWS
4. if ($opt_vardir eq $default_vardir) { .... use /dev/shm ... }
thus we have to realpath $default_datadir too, otherwise
the comparison logic might be broken

it's in the dead code (ifdef-ed out) so it doesn't matter what it is.

Let mtr handle SIGHUP the same way as SIGINT. This solves stale mysqld processes
